vices, ofwhich"thetollowing is a specification. c

This inventionrelates broadly ;to -tire-. chainattaching devices, and it has for its primary object to provide a connector-hook carried by anend of a: tire chain and atool whereby said hook maybe attached and detachedwith respect-to the opposite end of the chain;

A further object is to provide a connector hook for tire chains and a tool adapted to cooperate with said hookwhereby introduc- 2 tion in the latter of a link of the end of the chain opposite that by which the hook is carried is facilitated, to the end that the drawing of the chain into extremely close embracing relation to the tire is rendered possible.

A still further object is to provide a tirechain connector hook and a combination tool adapted to cooperate with said hook both in efi'ecting attachment and detachment of the latter with respect to an opposite end link of the chain.

In describin the invention in detail, reference is herein had to the accompanying drawings. in whichof a tire chain illustrating the connector hook and the therewith cooperating tool,

connector or coupling hook which is pivotally attached through the intermediacy of a pivot pin or rivet 2 with one-end of a side chain 3 constituting a part of a non-skid tire chain. Said hook is formed with a bill at; ,1 which has a slight upward inclination,

as shown, and which terminates in a rounded nose I. Said hook is designed for the recep tion of one of theend links of the opposite endol the chain 3, whereby said chain is secured in place upon a tire. The slot 4 in which said opposite endlink is received terminates at, a-distance from the free end of the hook approximating the internal length of the link, so that the link cannot become detached from the hook without first being swung to aposition out :of alinement with thelatter; and the edge 1 of said tree end'is preferably made substantiallystraight with the end in view, to prevent in large measure tendency of the attached link to swing by chance to detachingposition.

A bar or rod which constitutes a leverlike tool whereby the free end of the tire chain'may be engagedvwith and disengaged from the hook l in applying and removing the chain is indicated generally by the numeral 5. rod adjacent to'one end is a shallow-cup like socket 6 designed for the reception of the nose l of the hook. The tool has that portion thereof which is located directly adjacent to the socketed end bent downwardly into arcuately curved shape, forming a how 7. t

In'applying the chain to a tire, the'said bowed end of the tool is first passed through the link which is to be attached tothe hook 1, and then the socketed end thereof is seated upon the hook with'the nose 1* of the latter. received in the socket 6, as shown in Fig. 1. Then, employingcsaid nose as a fulcrum, the free end of the tool is elevated for gradually Formed in the under side of said advancing said link to a point where it passes over the socketed end and drops intov seated relation to said hook. As is obvious, a i very powerful leverage is obtainable through the use of said tool so that the chain may be drawn about the tire much more tightly than is possible in coupling the ends of chains by hand. T

A crosshead 8 is formed on the opposite end of the tool 5, and formed on opposite ends of said crosshead are short depending Referring to said drawings, 1 indlcat'es a disposed in engagement with the back of said hook, as shown in full lines in Fig. 2, tollowing which said tool is drawn rearward to swing the hook back to approximately the position shown in dotted lines in said figure, at which the said attached link is released.

As hereinhet'ore indicated, the tool de scribed aiiords means whereby the chain may be drawn so ti htly about a tire that chance disengagement o1 the link from seated relation tothe hookis rendered practicaliy impossible. Further, said tool provides means wherehy the ends of the tightly drawn chain may be conveniently uncoupled when desired.

Manifestly, the hook 1 may, if desired,

have associated therewith the usual swinging saddle-plate or-keeper whereby chance detachment of the hook from an attached end link of the chain is prevented.

What claimed is 1. The combination with a tirechain coupling-hook havinga bill at one end and provided with a hole in said end, of a chain coupling and uncoupling tool comprising a lever-like member having a shallow socket in the under side of one of its ends for receiving the end of said bill, and having a crosshead on its opposite end, said crosshead having a pair of prongs thereon, one'of said prongs being adapted for insertion in the hole in the hook and the other for seating against the back of said hook.

2. The combination with a tire-chain coupling-hook having a bill at one end and pr0- vided with a hole in said end, of a chain coupling anduncoupling tool comprising a le ver-like member having a shallow socket in the under side of one of its ends for seating upon the end of said. bill as a fulcrum and provided with a bow-like curvature rearward of said socket, the opposite end of said member having a crosshead with outwardly directed prongs thereon, one of said prongs being designed to enter the hole of said hook and the other thereof to seat against the back of said hook in effecting withdrawal of the latter from coupling position,

3. A combination tire-chain coupling and uncoupling tool comprising a rod having a socket in a side thereof adjacent to one end, a crosshead formed on the opposite-end of said rod, and prongs carried by the opposite ends of said crosshead. I

In testimony whereof, I affix my signature in presence of two subscribing witnesses.
